Abstract

A method and energy-efficient apparatus for the treatment of liquids through the joint use of a gas mixture-oxidizing agent and UV radiation. This method uses an excimer UV lamp performing two actions affecting the liquid and changing its properties with UV radiation and the generation of a gas mixture containing strong oxidizing agents for influence on the liquid, disinfection and purification of the liquid being treated from contaminants. The apparatus incorporates energy efficient design features to reduce energy consumption and operational costs, as well as an excimer lamp design that improves performance parameters to surpass and outlast existing devices. Unique electrode designs, cleaning systems, and materials combine to create a state-of-the-art liquid treatment apparatus that exceeds existing industrial analogs and norms.

Dependent claims

A system for treatment of a liquid, comprising:

two coaxial sleeves, an inner sleeve and an outer sleeve, wherein the inner sleeve is located inside the outer sleeve;
a first space between the inner and outer sleeve is filled with an excimer gas, forming a lamp, which irradiates an excimer UV radiation when a voltage is applied to two electrodes;
both sleeves made of rigid material transparent to the excimer UV radiation;
both sleeves are placed inside a reactor housing, the housing is coaxial with the sleeves;
the housing containing an inlet and outlet for the flowing liquid subjected to the treatment and a gas inlet and a gas outlet for a flowing gas mixture;
the liquid being treated is flowing inside the inner sleeve and is subject to treatment by the excimer UV radiation;
and
a second space between the outer sleeve and the housing contains the flowing gas mixture, which is also a subject to treatment by the excimer UV radiation at the same time as the liquid treatment;
the flowing gas mixture enters the second space between the outer sleeve and the reactor housing via the gas inlet and exits via the gas outlet;
oxidizing agents in the flowing gas mixture are produced under UV radiation action;
the flowing gas mixture with the oxidizing agents to be used for an oxidation of contaminants in the liquid;
the flowing gas mixture with the oxidizing agents passes through the liquid in a mixing chamber located downstream said excimer UV radiation treatment;
wherein a double function of the same excimer gas UV radiation is achieved simultaneously in the same system the liquid UV treatment and a generation of the oxidizing agents in the flowing gas.
